ECS服务器centos7.3下，tomcat下配置域名出错

tomcat下的server.xml文件配置：
改端口：

<Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
    <!-- A "Connector" using the shared thread pool-->
    <!--
    <Connector executor="tomcatThreadPool"
               port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
域名配置：
           <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h %l %u %t "%r" %s %b" />
      </Host>
      <Host name=120.79.179.91""  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
       <Content path="" docBase="/scweb/" debug="0" reloadable="false" crossContext="true" />
       <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="120.79.179.91_access_log." suffix=".txt"
               pattern="%h %l %u %t "%r" %s %b" />
        </Host>
        <Host name=www.smallpanghu.top""  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Content path="" docBase="/scweb/" debug="0" reloadable="false" crossContext="true" />
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="www.smallpanghu.top_access_log." suffix=".txt"
               pattern="%h %l %u %t "%r" %s %b" />
        </Host>
然后就启动tomcat失败了，日志报错为如下图所示；求大佬帮忙解决。
